156 N.M. Paramonov
included four species from genus Ptychoptera — P.peusi
Joost, 1974; P.contaminata (Linnaeus, 1758); P.lacustris
Meigen, 1830 and P.alina Krzeminski et Zwick, 1993.
Joost [1974] described P.peusi from upper part of river
Baksan (Central Caucasus) and has never been found
anywhere else.
The material for this paper is based on studying the
collections of Zoological Institute of Russian Academy
of Science, St. Peterburg.
MATERIAL EXAMINED. Russia, Karachaevo-Cherkesiya: 1 #
— Teberda zapovednik, 1300 m, 16.05.1964 (K.B. Gorodkov leg.);
Krasnodar Prov., Apsheronsk Distr.: 6 ## — river Mezmayka,
Kamyshanova Polyana, h~1200 m, 11.06–12.06.2004 (N.M. Paramonov
leg.); Georgia: 1 # — canyon Banis-Khevi, near Borzhomi,
27.06.1958 (V.N. Kurnakov leg.); 1 # — Bakhmaro, 15.07.1961
(A.K. Zagulyaev leg.); 11 ## — Abhaziya, Avadkhara, 1600–
2000 m, 5–14.06.1980 (A.K. Zagulyaev leg.).
According to these new records from the Main Caucasus
range, I define the range of P.peusi as mountain
Central-Northcaucasus or subalpine West-Caucasus
(Fig. 1). All material has been collected from altitude
1200–2500 metre high above sea level.
ECOLOGY. P.peusi inhabit canyon near water. I
collected imago in the stream fallen into the Mezmayka
in it up-stream. Silted stream, flows through the beechabies
forest (with a touch of hornbeam) with close
curtains, with ferns and mosses along the banks. The
most common plants of undergrowth were growth Abies
nordmanniana, Ilex sp., Rubus sp. From grasses Petasites
albus and Telekia speciosa was dominant.
According to Joost [1974] larvas and pupas of P.peusi
development on alluvial waterlogged ground, at a depth
of 5–10 cm. Water temperature is 6–8°C. On the little
altitude (1200–1600 m) the species lives of the forest
canopy, but in alpine zone (1600–2500 m) on the meadow.
ACKNOWLEDGEMENTS. The work was carried
